计算教学是新课程小学数学教学的重要组成部分。学生计算能力的高低,不仅直接影响其当前的数学学习能力,而且会影响到他们未来在生产、科研等领域的工作能力和今后的生活能力。需要特别指出的是,数学课程标准提出的数感、符号意识、空间观念、几何直观、数据分析观念、运算能力、推理能力和模型思想等的建立,在很大程度上有赖于计算教学和训练。因此,上好计算课,提高学 Computational teaching is an important part of the mathematics teaching of primary school in the new curriculum. The level of students’ computing abilities not only directly affects their current mathematics learning ability, but also affects their future ability of work in production, scientific research and other fields as well as their living ability in the future. What needs to be specially pointed out is that the establishment of mathematical sense, symbolic consciousness, spatial idea, geometrical intuition, data analysis conception, arithmetic ability, reasoning ability and model thought put forward by mathematics curriculum standard depends largely on calculation teaching and training . So, to do well to calculate class, improve learning
